payton collected data to show the relationship between the number of hours he practices and the number of errors he makes when playing a new piece of music. the table shows his data. practice makes better which is the approximate slope of the line of best fit for the data? -5.5 -4.5 -2.0 -1.0

Answer

Explanation:

Step1: Select two points

Let's choose the points ((1,36)) and ((8,5)) from the data.

Step2: Use the slope formula

The slope formula is (m=\frac{y_2 - y_1}{x_2 - x_1}). Substitute (x_1 = 1,y_1=36,x_2 = 8,y_2 = 5) into the formula: (m=\frac{5 - 36}{8 - 1}=\frac{- 31}{7}\approx - 4.43\approx - 4.5)

Answer:

(-4.5) (i.e., the second option)
